Abstract

PURPOSE: To maximize the overall air side heat transfer coefficient of a flat fin at the same fan power reference by setting the airstream direction row pitch of a heat transfer tube and the tube step pitch in a direction perpendicular to an airstream to specific dimensions.
CONSTITUTION: With respect to heat transfer tubes 12 each having an outer diameter of D0(3mm≤D0≤7.5mm), a tube row pitch L1 in the direction of an airstream 13 is set so satisfy 1.2D0≤L1≤1.8D0, and a tube step pitch L2 in a direction perpendicular to the direction of the airstream 13 is set to satisfy 2.6D0≤L2≤3.5D0. The heat transfer tubes 12 is rectangularly inserted through fin collars 14 provided in a plate-like fin 11, and are secured thereto by tube expansion working or brazing working. Further, in the platelike fin 11, leg parts 17a and 17b joined to the plate-like fin 11 of a slit group 16 having two sides opposing in the direction of the airstream 13 between respective heat transfer tubes 12, are provided by forming an angle with the normal line of the front edge of the plate-like fin. Thus, the flat fin of the base can exceedingly engance the air side heat transfer performance at the same fin power reference, and since the fluidity resistance of the airstream and a dead water zone are small, the air side heat transfer performance is improved.
